Looking to buy a corset which is more rigid to push up by boobs and look very dominant in the bedroom but I ask fellow people out there if you are still able to play easily during sex wearing one including pegging and spanking
Cottelli make some nice ones Matt black faux leather - I feel paired with matching thong will look amazing 
Yes You can still play during sex wearing one, Both My wife and I wear Corsets with attached suspenders regularly.
Spanking is fun both over knee and Kneeling on the bed, Not tried Pegging but I have seen videos of it done so it is possible.
A Quality Boned Corset is a Wonderful addition to any Lingerie Collection, Fun can be had putting it on as well as wearing.
I wear corsets a fair bit, both underboob and full coverage ones. It’s fine. I spank and peg in them, no issues at all. If you were to have any issues, just loosen it a tad, but I don’t envisage much.
I actually got married in one (as in outer garment), and I have sung in concerts in one. (Now singing in a corset is a challenge, especially when you are a soprano soloist).
Afew years ago a friend made me a corset. I loved wearing it. She only made them for men.
